06 Red Dog , US

Found in an Arctic region of Alaska , the Red Dog mine is the largest zinc-producing mine in the world . Operated by Teck Resources , the mine also produces lead and silver . The mine , which contains the biggest zinc deposits on Earth , produces around 10 % of the world ’ s zinc and is expected to operate until 2031 . The mine has been criticised for its environmental impacts , with a report from the US Environmental Protection Agency ( EPA ) stating that the facility releases more toxic materials into the environment than any other US facility . While the release of treated wastewater into river networks is permitted by law in Alaska , Teck faced legal action in 2016 for alleged pollution in the Wulik river . The EPA has nonetheless permitted the State of Alaska to remove the nearby Red Dog Creek and Ikalukrok Creek from its list of most-polluted waterways .
